ification checks performed by user applications in host computers. The
GCT in the FINS header is used by the system, and a verification error may
occur if it is used to perform verification checks in user applications, partic-
ularly when using CS/CJ-series CPU Units with unit version 2.0 or later.
1-6-6 Connecting Online to PLCs via NS-series PTs
Summary The CX-Programmer can be connected online to a PLC connected via a serial
line to an NS-series PT that is connected to the CX-Programmer via Ethernet
(see note 2). This enables uploading, downloading, and monitoring the ladder
program and other data.
Note 1. The NS-series PT must be version 3.0 or higher and the CX-Programmer
must be version 3.1 or higher.
2. Connection is not possible through an NS-series PT connected serially to
the CX-Programmer.
Connection Method In CX-Programmer, open the Change PLC Window and set the Network Type
to Ethernet. Click the Settings Button and set the IP address of the NS-series
PT on the Driver Tab Page. Also make the following settings on the Network
Tab Page.
• FINS Source Address
Set the local network address of the NS-series PT for the Network (exam-
ple network address: 1).
• FINS Destination Address
Network: Set the address to 111 if the PLC is connected to serial port A
on the NS-series PT and to 112 if it is connected to serial port B.
Node: Always set to 1
• Frame Length: 1,000 (See note.)
• Response Timeout: 2
Note Do not set the frame length higher than 1,000. If any higher value is used, the
program transfer will fail and a memory error will occur.
